For some reason the tension on the screws seems the same each time from the factory, yet I can feel a different tension if someone has had it apart before. In saying that, on closer inspection this evening with a torch, I noticed one of the screw heads has got marks on it, like someone has used the wrong sized screwdriver. I just emailled the guy I bought it from for some more info. > Now, if Apple were to use a thread-lock liquid/sealer like BMW does, it > would show up in a New York minute that someone had been tinkering with > the insides of the machine and you would have reason to suspect > evil-doings.

Everything else on the machine points to the label being correct, as from memory the 1Ghz machine in that series was a single processor (and this is definitely a DP). Even the serial number check with Apple says its a 1.25Ghz. I'm quite happy for it to be 1Ghz, as that is what I was told it was and paid for. My only concern is the machine is still under warranty for another 2 years and if the processors fry, Apple will ask questions when the parts are sent back (the processor board clearly says 1Ghz Dual Processor). Thanks for your input! Seeya Rod!
